3 Claims.

The present invention relates to new and useful improvements in water treating machines, and has for its primary object to provide, in a manner as hereinafter set forth, a unique apparatus for conditioning water to render it usable for repressuring in oil fields, whereby increased production will be had through what is commonly referred to as the flooding method.

Another very important object of the invention is to provide a machine of the aforementioned character wherein the pressure of the water to be treated is utilized for actuating the mechanism.

Still another very important object of the invention is to provide a machine of the character described comprising novel means for controlling or regulating the feed of the chemical which is mixed with the water.

Other objects of the invention are to provide a water treating machine of the character set forth which will be comparatively simple in construction, strong, durable, highly eincient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation of a water treating apparatus constructed in accordance with the present invention, showing a portion broken away in section.

Figure 2 is a vertical sectional view, taken substantially on the line 2-2 of Figure Figure 3 is a view in transverse section, taken substantially on the line 33 of Figure 2.

Figure 4 is a view in horizontal section, taken substantially on the line 4-4 of Figur 2.

Figure 5 is a detail view in side elevation of the adjustable crank arm.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a hopper I of substantially U-shaped transverse section, as shown to advantage in Figure 3 of the drawings. The hopper I, which includes a reremovable cover 2, is mounted on supp rting legs 3. Mounted in the hopper I is an agitator 4 comprising a shaft 5 having adjustably secured thereon a plurality of fingers 6. The shaft 5 is journaled in suitable bearings I which are provided therefor on the opposed walls 8 of the hopper I.

Mounted longitudinally beneath the hopper I and communicating therewith is a conduit 9. A screw conveyor I0 is operable in the conduit 9. The shaft I! of the screw conveyor I0 is journaled in suitable bearings provided therefor in the end members I2 of the conduit 9. The shaft II drives the agitator 4 through a chain and sprocket connection l3.

- One side of a stand I I is supported by certain of the hopper legs 3. Mounted on the stand I4 is a water power unit I5. The unit I5 includes a circular housing I 6 having journaled therein one end portion of a horizontal shaft I! which extends across the stand I4. Fixed on the shaft I! for operation in the housing I 6 is a water wheel I8. Rising from the housing I6 is an outlet I9 for connection with the source of water to be treated. An outlet 20 depends from the housing I6.

The conduit 9 has formed in one end p rtion a discharge opening 2I (see Fig. 2) for the chemical from the hopper I. A mixing receptacle or bowl 22 is provided for receiving the chemical from the conduit 9. Water under pressure is discharged with a whirlin motion into the bowl 22 by a tangential nozzle 23 for thoroughly mixing the chemical in said bowl.

waiving the chemical therefrom and An inclined conduit 24 receivesthe water from the outlet 20 Of the housing I6. The inclined conduit 24 passes beneath the bowl 22 for reis connected at 25 to a tank 26.

Journaled on certain of the hopper legs 3 is a horizontal shaft 21. The shaft I'I drives the shaft 21 through a chain and sprocket connection 28. Fixed on the shaft 21 is-a crank arm 29.

As illustrated to advantage in Figure 5 of the drawings, the crank arm 29 includes a pivotally adjustable bar 30 having fixed on its free end portion a laterally projecting pin 3|. Pitmans 32 have one end journaled on the pin 3|. An adjusting screw 33 for the bar 30 is threadedly mounted at 34 on the arm 29. One end portion of the adjusting screw 33 extends loosely through an apertured ear 35 on the bar 30. Washers 36 are provided on the adjusting screw 33 on opposite sides of the ear 35. Retaining nuts 31 anchor the adjusting screw 33 in the ear 35. The end portion of the adjusting screw 33 on which the elements 36 and 31 are mounted is reduced, as at 38, to provide a shoulder which one of said .elements 36 abuts.

The pitmans 32 are operatively connected to the shaft II of the screw conveyor I0 through 40. The device 40 comprises a ratchet wheel 4| which is fixed on the shaft ll. Levers 42 are journaled on the shaft H on opposite sides of the ratchet 4|. Pawls 43 are pivotally mounted on the levers Q2 and engaged with the ratchet 4|. The construction and arrangement, it will be observed, is such that when one of the pawls 43 is receding, the other of said pawls is moving orwardly for actuating the screw conveyor I0.

It is thought that the operation of the machine will be readily apparent from a consideration of the foregoing. Briefly, the chemical is placed in the hopper i and gravitates-intc the conduit 9, clogging being prevented by the agitator t. The water to be treated enters the housing It of the unit |5 at l8 and, in the arrangement shown, actuates the wheel H3 in a counterclockwise direction. This water, after it leaves the wheel 16, is discharged from the housing It at 20 and enters the conduit 24. The water flows down the inclined conduit 24 beneath the bowl 22 and is discharged into the tank 26, The shaft ii is turned by the water wheel l8 and drives the shaft 2? with the crank arm 29 thereon through the chain and sprocket connection 28. The crank arm 29, in turn, drives the screw conveyor l intermittently through the pitmans 32 and the double pawl and ratchet device 40'. Thus, the chemical from the hopper is moved in the conduit 9 to the discharge opening 2| through which it gravitates to the mixing bowl 22. From the bowl 22 the chemical gravitates to the conduit 24 where it is mixed with the water as said water flows to the tank 26. By adjusting the free end portion of the bar 30, with the pin 3| thereon, toward or away from theshaft 21 through the medium of the screw 83, the stroke of the pitmans 32 may be lengthened or shortened as desired. In this manner operation of the screw conveyor It) may be readily controlled for regulating the discharge of the chemical from the hopper The housing l of the unit i5 is provided with a vent M. A lock nut 15 secures the screw 33 in adjusted position.

It is believed that the many advantages of a water treating machine constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the apparatus is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of theinvention as claimed.
